I've just had a look at the frequency of my RS emails.
I got two "Thanks for registering" emails on the 3rd and 9th March.
Then I got "We're thinking of you" emails at intervals of 6-8-6-6-14-9 days. On a 6 day schedule, we're due another one this afternoon (GMT), otherwise I don't know when!
The "We're thinking of you" emails are pretty pointless, because they're generally the same. If the content had been a bit more thoughtful/helpful then they'd have been ok, otherwise you're left clicking on them in hope only to find generic good news that doesn't apply. Some lucky sods have had invitations to buy - look at the ebay offers that have RS labels on the boxes, but I've not had a whisper.
That said, I'd rather there IS an email now and then, if only to show that I've not fallen off their list!
I'm just a bouncer, splatterers do it with more force.....
